IMAGE SENSING DEVICE AND AUTOMOTIVE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240284061 titled 'IMAGE SENSING DEVICE AND AUTOMOTIVE DEVICE

The patent application describes an image sensing device with a pixel array consisting of multiple unit pixels, each with specific components. The driving unit controls the operation of each unit pixel, which includes photodiodes and floating diffusion regions.

Each unit pixel has a first region with a photodiode, first floating diffusion region, and second floating diffusion region, and a second region with a photodiode and a third floating diffusion region.
A floating diffusion (FD) connecting transistor is linked to one of the floating diffusion regions.
The driving unit can switch between normal operation, where individual unit pixels are operated, and binning operation, where at least two unit pixels are grouped and operated simultaneously.

Potential Applications: - This technology can be used in digital cameras, smartphones, and other imaging devices to improve image quality and processing speed. - Medical imaging equipment could benefit from this innovation by enhancing diagnostic capabilities and image resolution.

Problems Solved: - Enhances the efficiency of image sensors by allowing for simultaneous operation of multiple pixels. - Improves image quality and reduces noise in low-light conditions.
